Determination of the effect of NS-398 on cell apoptosis and expression levels of cyclooxygenase-2 (COX-2) and survivin in human hepatocellular carcinoma (HCC) cells by Western blotting. (A,B,C,D) Western blots and graphical representations demonstrating COX-2 and survivin expression levels in HCC cells treated with NS-398 and paeonol (Pae), with β-actin as internal control. Data are presented as mean ± standard deviation (SD) (**, P<0.01). Optical density (OD) values versus β-actin presented as fold change of the control values (*, P<0.05; **, P<0.01). (E) Concentration of prostaglandin E2 (PGE2) in treated cells compared with untreated cells measured by ELISA. Data are presented as mean ± SD of three independent experiments (bars = SD) (**, P<0.01). ELISA, enzyme-linked immunosorbent assay.
